HIGHLIGHTS
- What: The authors show that synchronizing one`s finger taps to metronomes at tempi outside of their preferred rate evokes larger pupil sizes a proxy for noradrenergic attention relative to passively listening. The study demonstrates the usefulness of considering participants` comfortable rates in experimental settings where tempo is manipulated because there could be latent yet systematic differences in the attentional demands among subjects. In sum, the authors provide evidence that the pupil signal can capture variations in attentional demands when synchronizing at different tempi.
- Who: Connor Spiech and colleagues from the DepartmentConcordia University, Montreal, QC . . .
